MMF of AC Distributed Winding: It has been seen earlier that the armature what-when-how.comof a practical machine has distributed winding wound for the same number of poles as the field…
Harmonic Analysis in Distributed Winding: The flux density wave of a synchronous machine is never exactly sine wave. Because of odd symmetry of poles (alternately north-south), the space Harmonic Analysis…
Synchronous Generator with Distributed Winding: Synchronous Generator with Distributed Winding - It may be seen from Eq. (5.7) that the flux/pole is limited by the machine dimensions and the peak…
Sinusoidally Distributed Current Sheet Concept: It was seen above that a distributed winding gives rise to a stepped mmf wave having a strong fundamental component which will be considered in…
Amplidyne (Rotary Amplifier) - Definition, Construction, Connection Diagram, Workings and Applications: The amplidyne is a rotary amplifier in which a small amount of power supplied to excite the field is…
Switched Reluctance Motor: The switched reluctance motor (SRM) has both salient pole stator and rotor, like variable stepper motor, but they are designed for different applications, and therefore, with different…
Self Controlled Synchronous Motor Drive Employing a Cycloconverter: Self Controlled Synchronous Motor Drive Employing a Cycloconverter as shown in Fig. 7.13. Firing pulses are generated either by comparison of the…
Three Phase Induction Motors: Three Phase Induction Motors are of two types: squirrel-case and wound-rotor. In squirrel-cage, the rotor consists of longitudinal conductor-bars shorted by circular connectors at the two…
